strip the kernel version suffix from target directories, except for brcm-2.4 (the -2.4 will be included in the board name here). CONFIG_LINUX_<ver>_<board> becomes CONFIG_TARGET_<board>, same for profiles.

+This patch adds support for the D-Link DSM-G600 Rev A.
+This is an ARM XScale IXP4xx system relatively similar to
+the NSLU2 and NAS-100D already supported by mainline. An
+important difference is Gigabit Ethernet support using
+the Via Velocity chipset.
+
+This patch is the combined work of Michael Westerhof and
+Alessandro Zummo, with contributions from Michael-Luke
+Jones. This version addresses review comments from rmk
+and Deepak Saxena.

+This patch is required as the frequency fixup in nslu2_init does not
+run sufficiently early in the boot sequence to take effect. In
+addition the dsmg600 setup code behaviour has been improved such
+that a 'fixup' routine is avoided.

++Informations about the Networking Driver using the IXP4XX CPU internal NPEs
++and Queue manager.
++
++If this driver is used, the IAL (Intel Access Library) must not be loaded.
++However, the IAL may be loaded, if this Modules are unloaded:
++ ixp4xx_npe.ko, ixp4xx_qmgr.ko ixp4xx_mac.ko
++
++This also means that HW crypto accelleration does NOT work when using this
++driver, unless I have finished my crypto driver for NPE-C
++
++
++Adoption to your custom board:
++------------------------------
++use "arch/arm/mach-ixp4xx/ixdp425-setup.c" as template:
++
++in "static struct mac_plat_info" adopt the entry "phy_id" to your needs
++(Ask your hardware designer about the PHY id)
++
++The order of "&mac0" and "&mac1" in the "struct platform_device"
++determines which of them becomes eth0 and eth1
++
++
++The Microcode:
++---------------
++Solution 1)
++ Configure "CONFIG_HOTPLUG" and "CONFIG_FW_LOADER" and configure
++ IXP4XX_NPE as module.
++ The default hotplug script will load the Firmware from
++ /usr/lib/hotplug/firmware/NPE-[ABC]
++ see Documentation/firmware_class/hotplug-script
++
++ You should take care, that $ACTION is "add" and $SUBSYSTEM is "firmware"
++ to avoid unnessecary calls:
++ test $ACTION = "remove" -o $SUBSYSTEM != "firmware" && exit
++
++Solution 2)
++ create a char-dev: "mknod /dev/misc/npe c 10 184"
++ cat the Microcode into it:
++ cat /usr/lib/hotplug/firmware/NPE-* > /dev/misc/npe
++ This also works if the driver is linked to the kernel
++
++ Having a mix of both (e.g. solution 1 for NPE-B and solution 2 for NPE-C)
++ is perfectly ok and works.
++
++ The state of the NPEs can be seen and changed at:
++ /sys/bus/platform/devices/ixp4xx_npe.X/state
++
++
++Obtaining the Microcode:
++------------------------
++1) IxNpeMicrocode.h in this directory:
++ Download IPL_IXP400NPELIBRARYWITHCRYPTO-2_1.ZIP from Intel
++ It unpacks the Microcode IxNpeMicrocode.c
++ Read the Licence !
++ Compile it with "gcc -Wall IxNpeMicrocode.c -o IxNpeMicrocode" on your host.
++ The resulting images can be moved to "/usr/lib/hotplug/firmware"
++
++2) mc_grab.c in this directory:
++ Compile and execute it either on the host or on the target
++ to grab the microcode from a binary image like the RedBoot bootloader.
++

+Add EEPROM notifiers
+
+These help board level code by allowing a callback when EEPROMs are
+loaded, this permits system level configuration to be loaded from the
+EEPROM. This is particularly useful when the ethernet MAC ids are
+stored in EEPROM and when the ethernet hardware is generic (so it
+has no board level knowledge), then the MACs can be loaded into
+the 'maclist' code and read out by the ethernet config.
